Asbestos is a mineral that was widely used in the building industry between the 1940s and 1980s because it was good at insulating and resisting heat. However, it has small fibres that can cause fatal lung disease if inhaled and has now been banned.
If your house was built before 1990 there's a good chance it contains some asbestos. The substance was banned in building products in 1990, but some houses built in the 1990s or early 2000s still used asbestos-containing products until a total ban came into effect in 2003.
Asbestos fibres can be deadly if inhaled as they can cause lung cancer, lung scarring and other lung conditions. Each year more Australians die of asbestos-related diseases than car crashes, so you need to take care when renovating if you suspect your home contains asbestos.
Loose asbestos fibres can be a risk to both tradespeople and people living in the home.
Asbestos was used in a wide range of products, from floor surfaces to insulation, and can be dangerous if disturbed.
Home owners often think of asbestos sheeting in walls or ceilings, but it can be found in nearly every room of the house, including:
The Queensland Government asbestos product gallery shows some of the more commonly used asbestos products.
You can also use our interactive tool to see where asbestos might be lurking in your home:
Consult a professional. You can't tell if a material contains asbestos just by looking at it. The only way to know for sure is to test a sample in a lab.
So, before you disturb or remove material that may contain asbestos make sure you get a sample tested.
A licensed remover can do the testing — find a list of licenced removers at Worksafe Queensland.
Asbestos fibres can create lung disease if inhaled.
This means it's vital you prevent asbestos fibres from becoming airborne by following safe work procedures if you are working with asbestos. This protects both the tradespeople doing the work and people living in the house.
Removing asbestos is licensed by Workplace Health and Safety.
The licence required depends on what type of asbestos you are removing:
This can be easily crumbled by hand when dry.
Common examples are acoustic ceilings and tiles, many types of plasters, wallboard, sprayed asbestos insulation, and pipe and boiler insulation.
As of 1 May 2021 Low Density Asbestos Fibre Board (LDB) has been re-classified as a friable asbestos material.
This contains a binder or hardening agent such as cement, asphalt or vinyl and is difficult to damage by hand.
Common examples are asphalt roofing shingles, vinyl asbestos floor tiles, asbestos cement sheets (fibro), and electrical switchboards.
You do not need a licence to remove less than 10m² of non-friable (bonded) asbestos, but you must take safety precautions and dispose of the waste safely.
Asbestos-containing material must be disposed of properly or hefty fines apply. You can't dump asbestos waste in:
Check with your local council for their rules on safely disposing asbestos-containing materials.

Queensland’s building industry watchdog has issued a public warning about Brisbane man Miroslav Bolfan in relation to building-related offences that include unlicensed and noncompliant electrical and plumbing work.
The Queensland Building and Construction Commission (QBCC) has issued the warning against Mr Bolfan and related business names that include MBN Australia, MBN, MBN Australia Bathroom Renovations and Tiling and MBN Cars.
Mr Bolfan has illegally used several different QBCC licence numbers, an expired licence number, and posed as two current QBCC licence holders by using their licence numbers.
The QBCC urges consumers, contractors and suppliers to be cautious in their dealings with Mr Bolfan and his businesses, and to exercise extreme caution and seek legal advice before making any payments, to protect their interests.
QBCC Commissioner, Brett Bassett, said that Mr Bolfan’s work was unlicensed and noncompliant, and posed a threat to public safety. “To help safeguard home owners, electrical and plumbing work must only ever be carried out by licensed individuals, which Mr Bolfan is not,” Mr Bassett said.
The QBCC is aware of several complaints about unlawful conduct by Mr Bolfan, and is concerned that he continues to carry out or undertake to carry out unlawful building work.
“We are also concerned that he continues to unlawfully advertise, pretends to be a licensee, fails to provide a compliant contract and takes excess deposits,” Mr Bassett said.
Mr Bolfan is believed to have performed work in Brisbane suburbs that include Bardon and Riverhills.
The QBCC strongly encourages consumers to only ever use appropriately licensed individuals, regardless of the size of a project,
The free licence check on the QBCC website will confirm if a person is licensed appropriately, and if necessary, consumers should ask for proof of a person’s identity.
The QBCC website also offers a free Find a Local Contractor search that allows consumers to find licensed, skilled tradespersons in their local area.
BACKGROUND
This warning is issued by the QBCC Commissioner to the public under section 20J(1)(i) of the Queensland Building and Construction Commission Act 1991.
Queensland’s building watchdog has issued a Public Warning about a Brisbane man for performing work outside his licence class, taking excessive deposits from home owners and failing to rectify defective work.
The Queensland Building and Construction Commission (QBCC) is urging consumers, contractors and suppliers to be cautious in their dealings with Matthew Todd Cooley and his businesses Renovations Brisbane Pty Ltd and Cooley M Services Pty Ltd, trading as Hire a Hubby Ascot (Qld).
The QBCC is aware of several complaints relating to Mr Cooley and his associated businesses, and warns anyone dealing with him and his businesses to exercise extreme caution, and to seek legal advice before making any payments, to protect their interests.
QBCC Commissioner, Brett Bassett, said the alleged offending had occurred in suburbs that included Balmoral, Norman Park, Hawthorne, Bulimba, Clayfield and Nundah.
He said complaints about building work by Mr Cooley and his businesses can be made by phoning the QBCC on 139 333.
“The QBCC strongly encourages consumers to always use the free licence check on the QBCC website to confirm that the person they are dealing with is appropriately licensed,” Mr Bassett said.
The QBCC website also offers a free Find a Local Contractor search, that allows consumers to find licensed, skilled, local tradespersons.
Mr Cooley is alleged to have undertaken building work outside of his QBCC licence class, taken deposits in excess of the maximum allowed under the QBCC Act and failed to comply with a QBCC-issued direction to rectify defective building work.

This Public Warning is issued by the Commissioner of the Queensland Building and Construction Commission (QBCC) under section 20J(1)(i) of the Queensland Building and Construction Commission Act 1991.
A common question builders ask is: What are the venting requirements for domestic kitchen range hoods in Class 1 buildings? In this article, we will inform readers of the purpose and installation requirements of such range hoods and some important issues for consideration.
A typical range hood found in a residential dwelling.
Range Hoods are primarily installed in a residential dwelling to improve the air quality in a kitchen by capturing and/or discharging things such as water vapour, odours, smoke, grease and other potential pollutants emanating from the use of a cooktop.
Without a functioning range hood, the discharges mentioned above can spread widely throughout the kitchen and adjoining rooms, resulting in a thin layer of difficult-to-remove grime deposited onto a range of surfaces.
Range hoods generally work on the principle of an electric exhaust fan being located above the cooktop that extracts fumes and pollutants from the cooking area. This is via a filter membrane that catches vapours containing grease and oils. Once filtered, the air is either recirculated back into the kitchen area or discharged to an external air-space.
The Building Code of Australia (BCA) contains no specific mandatory requirement that range hoods need to be installed in a Class 1 building.
What the BCA does require as an acceptable construction practice, is that natural ventilation is provided to any room being occupied by a person. Such natural ventilation can be provided via openable windows, doors or other devices of prescribed sizes relative to the room's floor area.
In circumstances where a window, door or another device cannot be located in a kitchen, the BCA also allows the borrowing of natural ventilation from adjoining rooms.
Range hoods need to be installed in strict accordance with the product manufacturer's instructions. A determination should be made when entering into a building contract (via the specifications) regarding whether a recirculating or exhaust type range hood installation is required.
Clearly, in cases where a client requires the range hood to be exhausting to outside air, additional costs will be incurred in material, installation costs for ducting, outlets, etc. Some range hoods may even require a more powerful motor to exhaust to a remote location.
Building contractors need to liaise with their clients and relevant suppliers/installers of the kitchen cabinetry and equipment to ensure that the range hood's location will allow for external exhaust if required by the client.
The most practical location to exhaust to outside air would be as close as possible to the range hood itself so that adequate venting can be achieved from the units fan motor. However, that may not always be practical so careful consideration of the exhaust outlet location is essential.
The practice of venting a range hood exhaust into a ceiling space or wall cavity is not sound. Over time, pollutants such as grease and oil can build up creating a fire hazard along with associated odours and potential damage to insulation and the like.
The cleaning or replacement of filters in range hoods is arguably one of the most overlooked pieces of routine maintenance required around a domestic dwelling.
If filters are not cleaned or replaced regularly, the range hood's efficiency will be degraded, and filters that are choked with flammable greases or oils become a potential high fire source risk.
Whilst we have only discussed the issues surrounding range hoods in Class 1 buildings, building contractors are reminded that in other building classes, special requirements apply to range hood installations and the Australian Standard AS 1668.2 - Mechanical ventilation in buildings is referenced by the BCA to ensure a compliant range hood installation standard.
Inadequate construction of roof flashing is a major cause of leaking roofs. It remains in the top ten defects identified by the Queensland Building and Construction Commission (QBCC) building inspectors.
The QBCC considers flashing and accessories defective if they leak under weather conditions anticipated by the Building Code of Australia (BCA).
The rectification costs of the defect and resultant damage can be significant for contractors and consumers.
Contractors are responsible for their standard of work and should be aware of correct roof flashing methods. The QBCC can direct contractors to rectify, not only defective work but consequential damage as a result of leaking roofs.
Defective roof flashing systems are a common cause of water penetration in roofs. Examples of roof flashings include:
It is essential to install a complete flashing system that intercepts, collects and discharges moisture or water back into the roof stormwater drainage system, not allowing moisture to enter the dwelling.
Apart from malleable flashings, which are fitted on-site, roof flashings should be purpose-made and machine-folded, of material compatible with all material used in the stormwater drainage system.
Both the Australian Standard 1562.1 Design and Installation of metal roof and wall cladding and the SA HB 39 Metal roof and wall cladding installation offer a comprehensive guide. Manufacturers also provide installation specification for their products.

When water can enter through a lap, it must be compressively sealed with an appropriate sealant.
The solutions provided are typical only and have been gathered from current and relevant building codes and Australian Standards. The methodologies described aim to achieve water-tightness by mechanical means rather than an over-reliance upon the use of sealants.
Building projects may often require the adaptation or development of ideas and solutions using the principles of sound waterproofing and flashing techniques as described in this fact sheet.
Note: Manufacturers of roofing and walling goods have developed specific design guides to assist the building industry in achieving compliance with the codes and standards. Readers are encouraged to take advantage of the manufacturer’s design guidelines where compliance with Australian Standard 1170.2 Structural design actions - Wind actions has been stated in their documentation.
Queensland’s building industry watchdog has issued a Public Warning about unlicensed fencer Graham James McKenzie, for alleged offences including taking excessive deposits and failing to perform any work.
Mr McKenzie’s trading names include Phoenix Fencing Constructions, Top Gun Fencing and McKenzie Fencing.
The Queensland Building and Construction Commission (QBCC) has launched legal proceedings against Mr McKenzie and urged property owners to avoid using him or any companies associated with him.
The QBCC is investigating an owner’s allegation that they paid a $10,000 deposit to Mr McKenzie in May for a retaining-wall project quoted at about $30,000 but work is yet to start.
QBCC Commissioner, Brett Bassett, said enquiries have also commenced into allegations that Mr McKenzie took four deposits in 2019 totalling almost $17,000 but did little, or no work.
Mr Bassett urged owners to only ever use QBCC-licensed contractors for building or renovation work, including fencing work, regardless of the size of the project.
This is the second recent QBCC Public Warning about a fencer, following the QBCC’s warning in November about Matthew Geoffrey Rixon.
In related news, a Gold Coast home owner who recently hired a fencer via an online service was left with a repair bill bigger than the cost of the original job, after the fencer botched and then abandoned the job, and also flooded the owner’s backyard.
The QBCC strongly encourages consumers to always use the free licence check on the QBCC website to confirm if a person is appropriately licensed.
The QBCC website also offers a free Find a Local Contractor search to help consumers locate a local, licensed and skilled tradesperson.
BACKGROUND
Deposits
Generally, if the cost of building work is $20,000 or more, the maximum deposit allowed is 5 per cent of the total contract price (including labour, materials and GST).
If the contract price is between $3,300 and $19,999, the maximum deposit is 10 per cent. An exception applies where more than 50 per cent of the value of the work is to be performed offsite (e.g. for kitchen renovations where the modules are custom-made in a factory), in which case the contractor is permitted to take up to 20 per cent deposit.
For jobs priced at $3,300 or less, the QBCC generally recommends no more than 20 per cent. For all contracts priced at more than $3,300, the number and timing of progress payments is a matter of negotiation between the owner and the contractor.
However, all progress payments must be related to the amount of work performed on site. For example, the contractor can't claim more than 50 per cent of the contract price, including the deposit, until at least 50 per cent of the work has been completed on site.
An overflow relief gully (ORG) is an essential element of the drainage system and unless there is an exemption, at least one shall be installed in a drain. It is intended to provide relief in the event of sewage surcharge, which is particularly important for the protection of property. There are specific requirements for an ORG and these are set out in the standard for sanitary plumbing and drainage, AS/NZS 3500 Part 2.
An ORG is to be located:
The top of the gully must not be enclosed and must have clear access for more than 2m above the grate. Discharging points over the ORG must also be carefully considered as not to affect the grate’s ability to be released in the event of a surcharge. The standard also provides alternative locations where it is not possible to conform to these requirements, for example, located within a building or recessed within an external wall. These alternatives should only be used in circumstances where it is impracticable to meet the four main requirements.
ORG heights are critical in terms of providing effective relief from sewage surcharge and to avoid excess water from entering the drainage system. The minimum height between the top of the overflow gully riser and the lowest fixture connected to the drain is 150mm and must be maintained at all times. The lowest fixture includes a floor waste gully. This is intended to prevent sewage from entering the building.
The minimum height between the top of the overflow of the ORG riser and the finished surface level shall be 75mm, except where the gully riser is located in a path or a paved area. In this case, it shall finish at a level to prevent ponding and ingress of water. Plumbers and drainers must also be aware of ORGs in flood-affected areas.
The standard provides that in areas subject to known flooding, the inlet to a sanitary plumbing and drainage system shall be positioned at least 150mm above the declared flood level. The inlet could likely be the top of the ORG. It is therefore important to know what the declared flood level is for the property you are working on. Plumbers and drainers ought to know what the declared flood level is for the property before starting work. This will ensure compliance with the standard and avoid the possibility of enforcement action for non-compliance. For information about flood levels, please contact the local government.
